1Apple iMac 21.5-Inch With 4K Retina Display (2015) : Front View

The 21.5-inch Retina display is the real star of this upgrade. With a resolution of 4,096 by 2,304, the In-Plane Switching (IPS) screen has 4.5 times the resolution of a 1080p HD display. That means you can have four 1080p HD video windows playing at native resolution simultaneously, or you can fill the screen with a 4K video from your iPhone 6s or other sources.

The exterior of the iMac looks identical to the 2014 model, with the same aluminum and glass body. It measures 17.7 by 20.8 by 6.9 inches (HWD) and weighs 12.5 pounds.
